Passenger Phusion not detecting Rails app under Apache

Question

In an Ubuntu 14.4 environment, am running Passenger under Apache to serve my Rails app.

After starting apache however:

$ passenger-status
Version : 5.3.3
Date    : 2018-08-10 17:08:52 -0400
Instance: DZeozT5t (Apache/2.4.7 (Ubuntu) Phusion_Passenger/5.3.3)

Phusion Passenger is currently not serving any applications.

$ passenger-config list-instances
Name                       PID      Description
--------------------------------------------------------------------------
DZeozT5t                   1438     Apache/2.4.7 (Ubuntu) Phusion_Passenger/5.3.3

It seems as if Passenger is installed and happily running, but not detecting my application.

$ cat /etc/apache2/sites-enabled/rails.conf 
<VirtualHost  *:80>
    ServerName url.com
    DocumentRoot /opt/members-only/public
    PassengerRuby /usr/local/bin/ruby
    <Directory "/opt/members-only/public">
        Allow from all
        Options FollowSymLinks
        Options -MultiViews
        Require all granted
    </Directory>
</VirtualHost>

My apache user is www-data

/opt/members-only is a soft link to the deployment directory ( a standard rails app)

$ ls -lash /opt/members-only/

There are no passenger related errors in /var/log/apache2/error.log

How can I get passenger to detect my application?

Answer 1

I had exactly the same problem. When going through this step by step deployment:

https://www.digitalocean.com/community/tutorials/how-to-deploy-a-rails-app-with-passenger-and-apache-on-ubuntu-14-04

I realized that I had not disabled the default site or enabled mine:

sudo a2dissite 000-default
sudo a2ensite testapp
sudo service apache2 restart
